Explanation lettering: C = shown as A · E = shown as B · D = shown as C · A = shown as D · B = shown as E

E is correct. NICE HTG758 defines strong compression for active venous leg-ulcer treatment as a system designed to deliver at least 40 mmHg at the ankle. This may be achieved with two- or four-layer bandaging, two-layer hosiery or a suitable wrap. It is distinct from maintenance hosiery after healing. The target is not uniform pressure along the limb, and safe delivery depends on limb shape, application skill, tolerance and prior arterial assessment. A number alone does not override contraindications such as significant arterial insufficiency or acute limb-threatening pathology.
